The Internet Archive discovers and captures web pages through many different web crawls.
At any given time several distinct crawls are running, some for months, and some every day or longer.
View the web archive through the Wayback Machine.

Content crawled via the Wayback Machine Live Proxy mostly by the Save Page Now feature on web.archive.org.

Liveweb proxy is a component of Internet Archive’s wayback machine project. The liveweb proxy captures the content of a web page in real time, archives it into a ARC or WARC file and returns the ARC/WARC record back to the wayback machine to process. The recorded ARC/WARC file becomes part of the wayback machine in due course of time.

Political TV ad archive preserves lies for the ages

The Internet Archive will help you call out politicians who stretch the truth.

You're about to see a lot of political TV ads in the US (if you haven't already), and keeping tabs on them is going to be... difficult. Who paid for which ad, who are they attacking, and who's playing fast and loose with the facts? That's where the Internet Archive wants to help. It's launching a Political TV Ad Archive that will use audio fingerprinting to track federal campaign spots in 20 markets spread across eight states. In addition to preserving videos, the collection will include info on where and when the ads have aired, their sponsors and their targets.

The launch doesn't officially take place until January 22nd, and it's safe to say that this isn't a comprehensive archive in its current form. You can't simply look up the ads in any given region, and this won't help for state elections. All the same, it should be that much easier to call out politicians and campaign donors when they lie through their teeth -- they won't get to pretend that a commercial didn't exist.
